Hi,
I am trying to implement the nsIURIContentListener interface and get
it registered so I can closely monitor URI changes before the location
is changed. I have added this interface to my "Chrome" class and
basically stubbed out all the methods. I then registered the interface
using SetParentURIContentListener. After that I put breakpoints on all
the methods included in nsIURIContentListener but none of them seem to
be called, even when the user clicks on a URL.
I am using Mozilla checked out of CVS about a week ago, since I had
problems getting older release versions building with my compiler
(VC++ 2005 express).
My main initialization looks like this (error checking removed to be
concise):
NS_InitEmbedding(nsnull, nsnull);
nsCOMPtr<nsIComponentRegistrar> registrar;
nsresult rv = NS_GetComponentRegistrar(getter_AddRefs(registrar));
if (NS_FAILED(rv)) return false;
rv = registrar->AutoRegister(nsnull);
mWebBrowser = do_CreateInstance(NS_WEBBROWSER_CONTRACTID, &rv);
mBaseWindow = do_QueryInterface(mWebBrowser, &rv);
chrome = new TestChrome();
chrome->AddRef();
mWebBrowser->SetContainerWindow(NS_STATIC_CAST(nsIWebBrowserChrome*,
chrome));
mWebBrowser->SetParentURIContentListener(NS_STATIC_CAST(nsIURIContentListener
*, chrome));
I have done some more digging and found that the call to
SetParentURIContentListener() is failing with rv = 80004005, so that
seems to be my core problem. Does anyone know why the registration may
fail in that way?
Thanks,
Craig.
